Shoe



Patented Nov. 19, 1935 UNITED STATES PATENT OFFICE 2 Claims.

My invention relates to shoes and deals more specifically with shoes having specially prepared soles designed to render the shoes more comfortable, and healthful as well as to enhance its 5 appearance.

For the purposes of this application, I shall show and discuss my invention in its adaptation to a welt shoe. It will be understood, however, that such treatment is purely illustrative and in l no way limiting. The construction of my shoe is described and illustrated in the accompanying specification and drawing and the characteristic features of novelty are particularly pointed out in the appended claims. Throughout the speci- 15 cation and drawing like reference characters are correspondingly employed, and in the drawing:

Fig. l is an exploded view of a shoe embodying the present invention.

2o Fig. 2 is a plan View of the intermediate sole used in this invention.

Fig. 3 is a transverse section of a completed shoe taken across the forward portion thereof.

Referring in detail to the drawing, the shoe 25 l5 having an upper il, a welt l2, and an insole I3 is assembled on a last I4. The upper is lasted and the welt is attached in the manner well understood in connection with the manufacture of welt shoes. l

30 An intermediate sole 20 is provided, having the tread portion thereof cut out by means of a suitable die, or otherwise to form a rand 2l integral with the shank and heel portion 22. I preferably use a blank of sole leather specially 35 treated to render the same soft and pliable. The opening defined by the rand 2l and the portion 22 may be any desired shape but I preferably shape it to be substantially coeXtensive with the tread surface of the outsole, leaving the rand 2i 40 which is of a width of about one half inch to one inch.

I now prepare a sheet 25 of latex or other suitable composition of the exact size and thickness to fit into the opening dened by the rand. The

45 sheet 25 closes the opening and thus provides anintermediate sole having a rubber or composition section. An outsole 3 together with the intermediate sole 26 are sewed to the welt I2, by stitching 40 thus positioning 20 in its inter- 50 mediate position, and enclosing the sheet of rubber 25 between the outsole 3e and the insole I3.

It is an important consideration in preparing the insole, upper, and welt structure that the edge |2a of the welt I2, which is sewed to the 55 upper and lip of the insole be trimmed. close to the bottom surface of the insole so that the welt finally lies in substantially the plane of` the bottorn surface of the insole, and the seam which joins welt, upper, and insole lip lies substantially flush with the bottom surface of the insole. 5 By virtue of this feature the lling commonly used in welt shoes is dispensed with, and in my structure the bottom surface of the welt and the insole contact in intimate relation with the intermediate sole.

At the tip of the toe portion however, in certain cases, I find it advisable to use a slight filling, due to the gathering' at this point of the upper, lining and welt, and the consequent diniculty in getting the flush relationship described above. For this purpose I preferably use a piece of sole leather l5 trimmed to the desired dimensions. It will be understood, of course, that this feature is not always necessary, for, depending on the character of materials used, I may obtain a suniciently flat structure at this point to preclude the use of this filler.

Following the attachment of the outsole it is merely necessary to trim the edges, attach the heel, and perform the other usual finishing operations.

Any suitable ller may be used in place of the sheet 25, such as ground cork, felt, or rubber compositions.

Having thus described my invention, I claim:

1. In a welt shoe, an insole having a lip, an upper, a welt, said upper and welt being' sewed to said lip, said welt when in the assembled shoe lying substantially in the plane of the bottom surface of the insole, an intermediate sole provided with a rubber section of a thickness substantially equal to that of the intermediate sole, and an outsole joined to said welt and said intermediate sole, the rubber section being normally in contact with the bottom surface of the 40 insole and with the top surface of the outsole.

2. In a welt shoe, an insole having a lip, an upper, a welt, said upper and Welt being sewed to said lip, said welt when in the assembled shoe lying substantially in the plane of the bottom surface of the insole, an intermediate sole comprising a rand section outlining an opening, an'd a section shaped to ll said opening and of a thickness substantially equal to the thickness ofsaid intermediate sole disposed within said opening, and an outsole joined to said welt and intermediate sole, said section being normally in contact with the bottom surface of the insole and with the top surface of the outsole. f
